IMHO, the biggest thing missing from sieve is the ability to easily use 
anti-spam software like Spamassassin ... but, not sure if I can consider 
that a failing of sieve itself, or the lmtp protocol ... there used to be 
software with Spamassassin called that acted as an lmtp 
proxy, and altho I'm using it, it doesn't fully handle the error codes 
that lmtp puts out ...

Some sort of 'plug in' for either lmtp, or sieve itself, would be nice, 
that allows for a 'clean' per user filtering ... amavisd is doing a 
quasi-per-user, but as far as I can tell, it only parses/processes the 
message once, so not 100% certain "which user" its basing its rules on ;(
